This is quite unusual in its design, but easy to use. Just put the battery's positive end on the right point, and attach the needle end, and it shows what percentage of power it has. Seems to be very accurate. ### ⭐⭐⭐⭐⭐ Great product *by J***Y on Reviewed in the United Kingdom on 12 November 2024* Does exactly what it is supposed to do. Good value. ## Frequently Bought Together - Dlyfull Universal Battery Tester with LCD Display Battery Checker Voltage/Power for AA AAA C D 9V 1.2V Alk & Rechargeable CR2032 CR123A CR2 CRV3 6V 12V 3.2V 3.7V 18650 1.5V/3V Button Cell Batteries - Kistenberg Battery Box KBB03 Battery Organizer - 115 Slots for Batteries, 295 mm x 195 mm x 70 mm - Nartel® LED Digital Battery Tester Battery Checker Multi Size for AA AAA C D 9V 1.5V Button Cell Batteries (Requires No Battery to Operate) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/674556410-dlyfulluniversal-battery-tester-with-lcd-display-battery-checker-voltage-power](https://www.desertcart.pt/products/674556410-dlyfulluniversal-battery-tester-with-lcd-display-battery-checker-voltage-power) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-08*
